Using three images from the Wide-field Infrared Survey Explorer (WISE) mission, students measure and analyze infrared light from objects to identify Brown Dwarfs and Ultra-Luminous Infrared Galaxies (ULIRGs). The lesson includes a teacher’s guide,...(View More) student worksheet and PowerPoint presentation (which contains the three images to be analyzed).(View Less)

These directions allow students to open different images that have been collected from the ROSAT satellite. The directions instruct the user to open the website, but first the user will need to install Hera software. (See related and supplementary...(View More) resources for a link to download Hera software at http://imagine.gsfc.nasa.gov/teachers/hera/install/install_hera.html).(View Less)

In this activity, students will use a simulator of an orbiting X-ray observatory to observe a supernova remnant, the expanding gas from an exploded star. They will take X-ray spectral data, analyze them, and answer questions based on that data. This...(View More) resource consists of a manual and software for the Introductory Astronomy Lab Exercise, from CLEA (Contemporary Laboratory Experiments in Astronomy). The manual includes introductory activities for students, background information, an instructor's guide, a student handout, an answer key, a software user's guide, and a glossary. The student section of the activity starts on page 13. See Related & Supplemental Resources for a link to download the software. Note: the software is only available for Windows.(View Less)

In this interactive, online activity, bias is explored when the students decide which of several sampling methods are biased. They see how bias affects the percentage of irregular galaxies determined to be in the sample from the Deep Field. After...(View More) completing this activity students will be able to analyze and identify sampling methods that reduce bias. Student may work independently or in small groups to complete each activity. This activity is apart of the online exploration, Galaxy Hunter. Detailed teacher pages, identified as Teaching Tips on the title pages of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards.(View Less)

In this interactive, online activity students elect a simple random sample to draw conclusions from data as presented in the Hubble Deep Field-North and Hubble Deep Field-South images. The optimal sample size is determined by exploring sample...(View More) variability, which is introduced through a min/max plot. The mean and median are added in order to pinpoint the spot where variability settles down and the measures of central tendency approach a constant value. The point where that first occurs is the smallest reasonable sample size. Students may work independently or in small groups to complete each activity. This interactive online activity is apart of the online exploration "Galaxy Hunter." Detailed teacher pages, identified as Teaching Tips on the title pages of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards. Use sample variability to determine optimal sample size.(View Less)

This interactive, online activity introduces the idea that everything emits electromagnetic radiation, including students. Students discover how the light emitted from an object (a robot) changes as the object is heated. A graph shows the amount of...(View More) light the robot emits in each wavelength region as the robot reaches higher temperatures. Students are challenged to relate the peak of the emitted light from the robot to the color it appears, thus connecting the temperature of an object with the color of light it emits. Students apply this information by plotting the peak wavelengths of four stars of their choice, and then determine the temperature of each. Upon completion of this activity, students will have identified peak wavelengths from graphical data and applied this concept to determine the relationship between temperature and star color. Students may complete this activity independently or in small groups. Detailed teacher pages, identified as Teaching Tips on the title page of the activity, provide science background information, lesson plan ideas, related resources, and alignment with national education standards. This activity is part of the online exploration "Star Light, Star Bright" that focuses on the electromagnetic spectrum and that is available on the Amazing Space website.(View Less)

In this assessment activity, students generate a data sample from either the Hubble Deep Field-North or Hubble Deep Field-South images, and compare the sample to data from the unselected field. This provides students with a real-life example of how...(View More) statistics can be used by scientists. After completing this activity students will be able to compare sample data with the population parameter to determine accuracy of sampling techniques and use statistical data to make conjectures about the universe. This interactive online activity is part of the online exploration “Galaxy Hunter”.

This online module includes three activities: Spiral Shapes, Elliptical Slide, and Imagine Irregular. By completing these activities, students discover that galaxies come in different shapes and learn about the process used by astronomers to...(View More) classify them. Additional background information is provided in the Galaxy Gossip and Galaxy Gallery sections of this module. Students may complete this activity independently or in small groups. This activity should be completed before Galaxy Games.

This activity is part of the online exploration "Galaxies Galore, Games and More" available on the Amazing Space website.(View Less)

This online module features an interactive model of the the Milky Way galaxy. Students click on parts of the model to read and learn about the different components of galaxies. Upon completion of this activity, students will be able to locate parts...(View More) of and build the Milky Way, and identify Earth's location within it. Additional information about our galaxy can be found in the Galaxy Gallery and Galaxy Gossip sections of the module. Students can complete this activity independently or in small groups. However, students should complete this activity prior to completing Galaxy Games.
